Model-Driven Engineering with Large Models in the Context of Product Line Engineering with IBYKUS AP

In software engineering practice models of software systems become more and more important and play a decisive role. Different model-driven approaches are followed by enterprises to achieve more efficient development techniques and higher flexibility. Practice has also shown that models reach a size and complexity that is hard to handle. Over the last years, IBYKUS, a midsized software vendor with focus on product line engineering in the domain of business, administration and governmental processes, has put an effort into the development environment IBYKUS AP which supports model-driven engineering. This paper describes the state of the used techniques on a conceptual level in the first part. The idea of incremental modeling and editable model views is presented in the second part accompanied with research questions to be tackled in future.
